Some of the items up for grabs include English George Smith upholstered furniture, a set of embroidered yellow silk Louis XV armchairs, and an 18th century Louis XVI chest that's valued between $30,000 and $50,000. The auction will be hosted by Kaminski Auctions on November 2 at the Santa Barbara Polo Club and Racquet Club in California. Proceeds will go towards the Oprah Winfrey Leadership Academy Foundation College Fund for the graduates of her South African school for girls.
